STREET MARKER Filed May 7, 1929 JAnggs s. GEORGE INVENTOR Patented Sept.23, 1930 UNITED STATES PATENT OFFICE JAMES S. GEORGE, 0F WATERBURY,OONNECTIOUT, ASSIGNOB, TO SCOVILL MANUFAC- TUBING COMPANY, OF WATEBBURY,CONNECTICUT, A. CORPORATION OF CON- STREET WEB Application filed may 7,1829. Serial No. 361,027.

This invention relates to improvements in street markers, that is,devices now Widely used arranged to be embedded in the street or otherplace to provide directionsfor the proper control of trafiic or forother purposes.

In certain types of these markers, the

marker'consists of a head provided with legs and with devices forexpanding or spreading the legs into engagement with the pavement, ahole being first made in the pavement for the reception of the shank.With devices of this type, it frequently happens that the holes arecarelessly bored and are of an improper depth, so that when it isattempted to set the marker in position, there is no bottom for thespreading device to act against, with the result that engagement of theholding legs with the pavement is not accomplished. This is particularlydisadvantageous where the marker is to form part of a design, and it isnecessary to bore another hole, thus throwing that marker out of place.

The especial object of the present invention is to provide a markerhaving holding legs together with a spreading device which will act tospread the legs into engagement with'the pavement regardless of thedepth of the hole which has been bored to receive the shank and legs ofthe marker.

A further object of the invention is to provide a spreader constructionwhich will act to lock the parts in position, so that the legs cannotspring back after they have once been set and thus loosen the marker.

With these and other objects not specifically referred to, the inventionconsists in certain novel parts, arrangements and com.-

binations which will be described in connec- 6 tion with theaccompanying drawings and the novel features pointed out in the claimhereunto appended.

Referring to these drawings Figure 1 is a plan view of, the improvedmarking device;

Figure 2 is a sectional. view showing the marker in position in thepavement, with the parts not set; and

Figure 3 isa sectional vievy similar to Fig. 2, showing theparts ofthe-marker in set position.

Referring to said drawings, the pavement is indicated by the letter P,and in' the pavement is formed, as by boring, a hole H, this hole beingdesigned to receive the locking parts of the marker.

The marker itself is made of metal and comprises a head 2, the'top ofwhich is preferably rounded, as at 3, so that there is no obstruction toanything assing over it. The under face of this head is flat, orsubstantially'flat, as indicated at 4:, so as to lie fiat against thepavement. This head has asso- Y ciated therewith a shank 5 which isdivided, as by slitting the metal, into spaced holding fingers 6. Thenumber of these fingers may, of course, be varied, but in the particularconstruction illustrated, there are four of these. The outer faces ofthese fingers are plain, as indicated in the drawings, and the innerfaces are formed with inwardly and downwardly extending cam faces 7which terminate in a sharp edge 8, the faces of the leg below the edge 8facing downwardly and outwardly, as indicated at 9, forming 1n effeetashoulder. The head is provided with an opening or aperture 10, and theshank is formed with'a recess 11. Cooperating with this head and shankis an improved spreading device shown in the form of a metal rod 12which may be of the same metal or a difierent metal from that of whichthe head is composed. This rod 12 at its lower end is provided with aconed end 13 above which is a shallow groove 1 1 forming a shoulder 15.The coned end is of greater diameter than the opening between the inneredges 8 of the legs 6, so that when the rod is driven into position bythe application of pressure to the upper end thereof, the coned end actsto spread the legs 6 from the position shown in Fig. 2- to that shown inFig.

. 3, and this causes the legs to engage the pave- V edges 8, these willengage the shoulder 15 made without departin ficient size to be readilyvisible at considerable distances, said head having an aperture and arelatively large fiat under face, a relatively slender shank dependingfrom. said head for entering a hole in a pavement, said shank havingholding fingers arranged in a generally circular manner and a recess inline with the aperture in the head, said fingers having inner faces withinwardly and downwardly extending cam faces terminating in sharp loweredges and shoulders beow said edges, and a rod having a coned portionand a shoulder above said coned ortion, said rod being adapted to bedriven 1nto said aperture and recess and. the coned portion to exert asliding wedging action on the cam faces whereby the fingers are forcedoutwardly in a radiating fashion into engagement with the pavement andthe flat face drawn against the pavement surface, the shoulder on therod lockingly engaging the shoulders of said fingers after the rod hasbeen driven in.

In testimony whereof,'I have hereunto set my hand.
